Answer:
<em>C) $46.80</em>
Explanation:
The price of new shoes = $85
The amount paid for the shoes = $ 40
The balance amount for the shoes = $85 - $40 = $ 45
The rate of interest = 8%
The time period = 6 months = 0.5 years
Simple interest:
Simple interest = = $1.8
So, Amount = Principal + Interest
or, Amount = $45 + $1.8 = $ 46.8
<em>The balance amount owned in six months is $46.8</em>
THE answer is 17 because 2X2= 4+13= 17
Your Welcome :D
90 volume because 3 multiples by 30 = 90
Answer:
c) 6x - 5y = 15
Step-by-step explanation:
Slope-intercept form of a linear equation: 
(where m is the slope and b is the y-intercept)
Maria's line: 
Therefore, the slope of Maria's line is 
If two lines are perpendicular to each other, the product of their slopes will be -1.
Therefore, the slope of Nate's line (m) is:

Therefore, the linear equation of Nate's line is:

Rearranging this to standard form:



Therefore, <u>option c</u> could be an equation for Nate's line.
Answer:
The best point of estimate for the true mean is:

Since the time can't be negative a good approximation for the confidence interval would be (0,5.248) minutes. The interval are tellling to us that at 95% of confidence the average late time is lower than 5.248 minutes.
Step-by-step explanation:
Information given
represent the sample mean for the late time for a flight
population mean
represent the population deviation
n=76 represent the sample size
Confidence interval
The best point of estimate for the true mean is:

The confidence interval for the true mean is given by:
(1)
The Confidence level given is 0.95 or 95%, th significance would be
and
. If we look in the normal distribution a quantile that accumulates 0.025 of the area on each tail we got
Replacing we got:
Since the time can't be negative a good approximation for the confidence interval would be (0,5.248) minutes. The interval are tellling to us that at 95% of confidence the average late time is lower than 5.248 minutes.
